Luis Severino struggling with slider

His slider is one part of the problem. I’ve watched a few of his starts. What I noticed is his fastball location is off. He’s catching too much of the middle of the plate. To verify I looked at his fastball heatmaps on Baseball Savant. Here’s what I found:

Edit: Missed the labels somehow. On the left is Severino’s fastball before July 2nd; on the right is his fastball after July 2nd.

A slider, which isn’t breaking as much, mixed with a straight fastball, which is finding too much of the plate, is a bad combination.

Jim, could you provide a link to the Baseball Savant source? I don't know exactly how to read these heatmaps (what does the scale on the right hand side of each chart represent, for example?) and couldn't find the originals on Baseball Savant.

He should throw a few to Cerrano.

@1-- I don't have a link to the source, but looking at the two maps, my first guess (which may certainly be wrong) is that the scales on the right are counts of pitches-- the darker the particular spot, the more pitches hit that location. That doesn't really correlate to the numbers on the scale, but it's the first thing I thought of that sort of makes sense.

The scale on the right is the heat duh.
